Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 137,370,445, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 137,370,445 | |
| -1 | -137,370,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 137,370,445.
Example:
1 x 137,370,445 = 137,370,445
and
-1 x -137,370,445 = 137,370,445
Notice both answers equal 137,370,445
With that explanation out of the way, let's continue. Next, we take the number 137,370,445 and divide it by 2:
137,370,445 ÷ 2 = 68,685,222.5
If the quotient is a whole number, then 2 and 68,685,222.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 137,370,445 | |
| -1 | -137,370,445 |
Now, we try dividing 137,370,445 by 3:
137,370,445 ÷ 3 = 45,790,148.3333
If the quotient is a whole number, then 3 and 45,790,148.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 137,370,445 | |
| -1 | -137,370,445 |
Let's try dividing by 4:
137,370,445 ÷ 4 = 34,342,611.25
If the quotient is a whole number, then 4 and 34,342,611.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 137,370,445 | |
| -1 | 137,370,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 71 | 355 | 379 | 1,021 | 1,895 | 5,105 | 26,909 | 72,491 | 134,545 | 362,455 | 386,959 | 1,934,795 | 27,474,089 | 137,370,445 |
| -1 | -5 | -71 | -355 | -379 | -1,021 | -1,895 | -5,105 | -26,909 | -72,491 | -134,545 | -362,455 | -386,959 | -1,934,795 | -27,474,089 | -137,370,445 |
